Description

詢答機系統Answering machine system

本發明係有關一種詢答機系統，其可在至少一設置於定子上之讀取線圈構成的靜止側，與至少一設在轉軸上之詢答線圈構成的轉動側之間進行無接觸之感應能量傳輸。此種詢答機系統在日常生活中之重要性越來越高。其可在一被動裝置中作為識別及記憶體，或在一主動裝置中處理感測資料，無線資料傳輸使得所使用及控制之資料可雙向傳輸。小型化自主測量系統在技術上已可實現，市面上已出現多種詢答電路及系統。The present invention relates to an interrogator system that can perform contactless sensing between a stationary side of at least one read coil disposed on a stator and a rotational side of at least one interrogation coil disposed on a rotating shaft. Energy transfer. Such an answering machine system is becoming more and more important in daily life. It can be used as a recognition and memory in a passive device, or to process sensing data in an active device, and the wireless data transmission enables the data used and controlled to be transmitted in both directions. Miniaturized autonomous measurement systems are technically achievable, and a variety of acknowledgment circuits and systems have emerged on the market.

DE 199 24 830係提出一種詢答機系統，其係用於測量車輛輪胎溫度與空氣壓力及監控磨損。溫度及壓力的測量係藉助一在硫化輪胎中的電子詢答機，其可應一收發報機之要求，以一數位載頻法將測量值經一徑向整合在輪胎上設作扁平線圈之詢答線圈傳輸至安裝在車輛上具一發射線圈之收發報機。詢答機一般由一或數個矽晶片與一些外部元件構成，該矽晶片上整合有溫度感測器、微機械壓力感測器、一微處理器及所屬之解析與傳輸電子元件。收發報機與詢答機之間的通信為數位式，收發報機發送命令至詢答機，詢答機例如以進行測量、補償及線性化測量值以及傳輸測量資料及/或其他儲存在詢答機中的資料作為應答。DE 199 24 830 proposes an interrogator system for measuring vehicle tire temperature and air pressure and monitoring wear. The temperature and pressure are measured by means of an electronic interrogator in a vulcanized tire, which can be integrated into the tire by a digital carrier frequency method as a flat coil in accordance with the requirements of a transceiver. The inquiry coil is transmitted to a transceiver mounted on the vehicle with a transmitting coil. The answering machine generally consists of one or several silicon wafers and some external components. The germanium wafer is integrated with a temperature sensor, a micro mechanical pressure sensor, a microprocessor and associated analysis and transmission electronic components. The communication between the transceiver and the answering machine is digital, and the transceiver sends a command to the answering machine, for example, to measure, compensate, and linearize the measured value and transmit the measured data and/or other stored in the query. The information in the machine is answered.

進行程序監控之感應器或最佳化程序之主動件亦為工具機製造不可或缺。測量值記錄器主要安裝在可被方便接觸之處。為旋轉件時，例如轉軸，轉子之物理特性只可間接由定子測得。無線傳輸法雖已普遍使用，但機械製造之需求為使該種系統自主工作。故資料傳輸尚須能量耦合，尤其是以感應方式。此處習知方法，例如使用答詢技術，無法被簡單地適配，因該系統在研發時對機械製造之特殊要求的考量不足。The active component of the sensor or optimization program for program monitoring is also indispensable for machine tool manufacturing. The measured value recorder is mainly installed where it can be easily accessed. In the case of a rotating part, such as a rotating shaft, the physical properties of the rotor can only be measured indirectly by the stator. Although the wireless transmission method has been widely used, the demand for mechanical manufacturing is to make the system work autonomously. Therefore, data transmission still requires energy coupling, especially inductive. Conventional methods herein, such as the use of answering techniques, cannot be easily adapted because the system has insufficient consideration of the special requirements for mechanical manufacturing during development.

例如因渦流損耗及其他附生作用出現信號干擾，而使資料傳輸變得極為困難。其他因素為資料傳輸方面的複雜容量與電阻變化以及幾何與材料感應變化。For example, signal interference occurs due to eddy current losses and other epiphytic effects, making data transmission extremely difficult. Other factors are complex capacity and resistance changes in data transmission and changes in geometry and material sensing.

為避免此種干擾，DE 196 10 284係提出一種天線線圈，其具至少一匝。該線圈之一側設有一屏障，其覆蓋導電環線並構成一開環。如此可減少電性干擾場之影響。以一頻率選擇電路搭接屏障之中斷亦可抑制電磁干擾場之影響。In order to avoid such interference, DE 196 10 284 proposes an antenna coil having at least one turn. One side of the coil is provided with a barrier covering the conductive loop and forming an open loop. This reduces the impact of the electrical interference field. Interruption of the lapped barrier with a frequency selection circuit can also suppress the influence of the electromagnetic interference field.

設計感應耦合系統時，周圍環境之材料扮演一重要角色。因線圈電阻會隨頻率及材料之電磁特性改變。產生的交變場會在材料中產生渦流損失，使得旋轉系統之功率輸入變難。感應耦合系統一重要特徵為線圈之耦合，其應達一最高耦合係數。故振蕩回路品質越高時，次級線圈需要的電流就越小，因損失減少。實際應用時，詢答線圈之功率一般例如為5V，10mW，讀取線圈之電流則只為170mA。When designing an inductive coupling system, the material of the surrounding environment plays an important role. Because the coil resistance changes with the frequency and the electromagnetic properties of the material. The resulting alternating field creates eddy current losses in the material, making the power input to the rotating system difficult. An important feature of the inductive coupling system is the coupling of the coil, which should reach a maximum coupling coefficient. Therefore, the higher the quality of the oscillation circuit, the smaller the current required by the secondary coil, and the loss is reduced. In practical applications, the power of the inquiry coil is generally 5V, 10mW, and the current of the reading coil is only 170mA.

本發明之目的在於改良此種詢答機系統，使得讀取線圈之環境，尤其是定子，由一具低磁導率之良好導電材料構成，尤其是鋁，且/或在詢答線圈處的定子內壁設一層由高導磁率材料構成的薄膜。The object of the invention is to improve such an interrogator system such that the environment in which the coil is read, in particular the stator, consists of a good electrically conductive material of low magnetic permeability, in particular aluminum, and/or at the interrogation coil. A film made of a high magnetic permeability material is provided on the inner wall of the stator.

本目的由本發明詢答機系統如下而達成：讀取線圈之環境，尤其是定子，由一具低磁導率之良好導電材料構成，尤其是鋁。The object is achieved by the inventive answering machine system in that the environment in which the coil is read, in particular the stator, consists of a good electrically conductive material with a low magnetic permeability, in particular aluminum.

定子由鋁製成時有兩種作用，其一為會降低詢答線圈之電感，其係由於良好導電之鋁中的渦流損失所致。但令人意外的是，線圈阻抗及損失功率亦同時明顯下降。如此而有利地提高詢答線圈之品質及靜止與轉動側間之功率傳輸。由於並聯諧振回路之較佳品質，共振時之功率接受及過壓明顯優於非鋁製的定子。故詢答線圈要有固定功率時，讀取線圈需要一較低電流。因此電流密度降低，使得讀取線圈亦可具一較小尺寸。When the stator is made of aluminum, it has two functions, one of which is to reduce the inductance of the inquiry coil, which is caused by eddy current loss in the well-conductive aluminum. Surprisingly, however, the coil impedance and power loss are also significantly reduced. This advantageously increases the quality of the interrogation coil and the power transfer between the stationary and rotating sides. Due to the better quality of the parallel resonant circuit, the power acceptance and overvoltage at resonance are significantly better than those of non-aluminum stators. Therefore, when the inquiry coil has a fixed power, the coil needs a lower current. Therefore, the current density is lowered, so that the reading coil can also have a small size.

詢答線圈及/或讀取線圈設作扁平線圈時，可有利地降低線圈製造成本。且此種扁平線圈的體積小。其亦可在稍後有利地安裝在現有機械上。When the polling coil and/or the reading coil are designed as flat coils, the coil manufacturing cost can be advantageously reduced. And such a flat coil has a small volume. It can also be advantageously installed on existing machines at a later time.

讀取線圈設在一U形芯體上時可達到高磁通量。且製造成本低，因此種芯體為一般市售芯體。High magnetic flux is achieved when the read coil is placed on a U-shaped core. Moreover, the manufacturing cost is low, and thus the seed core body is a generally commercially available core body.

詢答線圈及/或讀取線圈設作扁平線圈固定在定子及/或轉子圓柱形周壁內側及/或外側時，線圈之組裝特別容易。The assembly of the coils is particularly easy when the interrogation coils and/or the read coils are arranged such that the flat coils are fixed to the inside and/or outside of the cylindrical and/or cylindrical cylindrical walls of the rotor.

詢答線圈及/或讀取線圈固定在定子及/或轉子頂壁內側及/或外側時，可使線圈之間達到特別良好之耦合。此種組裝方式之缺點為轉軸需要一自由端。此種組裝方式特別有利的是使用具鐵氧芯之線圈。此處由於高磁通量而可達到良好的耦合。When the interrogation coil and/or the reading coil are fixed to the inside and/or outside of the stator and/or the top wall of the rotor, a particularly good coupling between the coils is achieved. A disadvantage of this type of assembly is that the shaft requires a free end. This type of assembly is particularly advantageous in that a coil with a ferrite core is used. Good coupling is achieved here due to the high magnetic flux.

扁平線圈，尤其是印刷有導線之薄膜，設作自黏式時，可大為簡化扁平線圈之組裝。Flat coils, especially those printed with wires, are designed to be self-adhesive, which greatly simplifies the assembly of flat coils.

大部分被測量之轉軸皆為高合金MnCr鋼或一般工具鋼。靜止與轉動件之間的功率傳輸可大為改善，如扁平線圈與轉子或定子之間設一層高磁導率材料構成的薄膜，尤其是非晶態金屬薄膜或不導電鐵氧金屬薄膜。其作用為使磁通量被鐵氧引導，而使得較少寄生渦流出現在環境金屬材料中。Most of the shafts being measured are high alloy MnCr steel or general tool steel. The power transmission between the stationary and rotating parts can be greatly improved, such as a film made of a high magnetic permeability material between the flat coil and the rotor or the stator, especially an amorphous metal film or a non-conductive ferrite film. Its function is to direct the magnetic flux by the ferrite, so that fewer parasitic eddies flow out of the current environmental metal material.

高磁導率材料構成之薄膜的厚度為0.01至1mm便已足夠。A film made of a high magnetic permeability material has a thickness of 0.01 to 1 mm.

讀取線圈比詢答線圈寬時較為有利。詢答線圈在轉軸軸向上的寬度例如為3mm，設在一U形鐵氧芯上的讀取線圈例如為20mm時，便足以供應一微型系統。It is advantageous to read the coil wider than the inquiry coil. The width of the interrogation coil in the axial direction of the rotating shaft is, for example, 3 mm, and when the reading coil provided on a U-shaped ferrite core is, for example, 20 mm, it is sufficient to supply a micro system.

將扁平線圈設作旋轉對稱平面線圈，尤其是多層式時，可達到一均勻的能量傳輸。藉多層式平面線圈可使電感及匝數簡單配合需求，故詢答線圈可有利地配合微型系統需要的供應電壓及負載電阻。When the flat coil is designed as a rotationally symmetric planar coil, especially in a multi-layered manner, a uniform energy transfer can be achieved. Multi-layer planar coils can be used to easily match the inductance and the number of turns, so the query coil can be advantageously matched with the supply voltage and load resistance required by the micro system.

扁平線圈由一具平行導線可被任意截斷之薄膜帶構成時，詢答線圈的適配特別簡單，其導線末端在彎成圓筒形後偏移一距離，藉靠攏接觸而構成線圈。When the flat coil is composed of a film strip whose parallel wires can be arbitrarily cut off, the adaptation of the coil is particularly simple, and the end of the wire is offset by a distance after being bent into a cylindrical shape, and the coil is formed by the close contact.

扁平線圈設在轉軸及/或定子一環溝中時，線圈可被有利保護而定位於其軸向位置上，故即使振動時亦不會偏移。When the flat coil is disposed in the rotating shaft and/or the stator ring, the coil can be advantageously protected and positioned in its axial position, so that it does not shift even when vibrating.

高磁導率薄膜之磁導率高於線圈周遭之轉軸及/或定子材料之磁導率時，可適當選擇設在線圈與其金屬環境間之薄膜的材料。When the magnetic permeability of the high magnetic permeability film is higher than the magnetic permeability of the rotating shaft and/or the stator material around the coil, the material of the film disposed between the coil and its metal environment can be appropriately selected.

在一特佳實施例中，轉軸由鋼製成，尤其是CrMn鋼，並將尤其是由旋轉對稱扁平線圈構成之詢答線圈設在一由非晶態金屬構成的薄膜上。所有試驗皆證明此種組合可達到最佳功率傳輸。讀取線圈中之電流可降低為1/5。In a particularly preferred embodiment, the shaft is made of steel, in particular CrMn steel, and the interrogation coil, in particular composed of a rotationally symmetric flat coil, is placed on a film of amorphous metal. All tests have demonstrated that this combination achieves optimal power transfer. The current in the read coil can be reduced to 1/5.

定子由鋁製成並將尤其是由旋轉對稱扁平線圈構成之讀取線圈設在一鐵氧薄膜上的組合可得到有利的良好耦合。The stator is made of aluminum and a combination of a read coil, in particular composed of a rotationally symmetrical flat coil, on a ferrite film provides advantageous good coupling.

該耦合在某些情形下可被更進一步改良，如定子及/或轉子與鐵氧薄膜之間再設另一由良好導電材料，尤其是銅，構成之薄膜。This coupling can be further improved in some cases, such as another film made of a good conductive material, especially copper, between the stator and/or the rotor and the ferrite film.

最後有利的是，使讀取線圈捲繞在一鐵氧芯上並使設在定子內壁由一高磁導率材料或鐵氧材料構成之薄膜在讀取線圈處中斷。Finally, it is advantageous if the reading coil is wound on a ferrite core and the film provided on the inner wall of the stator from a high magnetic permeability material or a ferrite material is interrupted at the reading coil.

本發明之其他細節、優點及特徵將配合下述圖式所示一較佳實施例而加以說明，其中相同元件標示相同符號。Other details, advantages, and features of the invention will be described in conjunction with the preferred embodiments illustrated in the drawings.

圖1至圖4係顯示讀取及詢答線圈之不同示意圖。Figures 1 through 4 show different schematic diagrams of the read and answer coils.

圖1中捲繞於一罩形或E形鐵氧芯23之讀取線圈2與一旋轉對稱捲繞之詢答線圈4對立。詢答線圈之導線14為一捲繞在具U形截面之環形芯體24上的繞組。The read coil 2 wound in a cap-shaped or E-shaped ferrite core 23 in Fig. 1 opposes a rotationally symmetrically wound interrogation coil 4. The wire 14 of the interrogation coil is a winding wound around a toroidal core 24 having a U-shaped cross section.

U形自由邊25對準E形鐵氧芯23之中間及外側邊25。The U-shaped free edge 25 is aligned with the middle and outer sides 25 of the E-shaped ferrite core 23.

圖2係顯示一旋轉對稱之軸向配置實施例。詢答線圈4固定在轉子11頂壁13，讀取線圈2則同軸固定於定子1頂壁12。讀取及詢答線圈之兩導線捲繞在相對罩形鐵氧芯26之中心柱上。Figure 2 shows an embodiment of an axial configuration with rotational symmetry. The inquiry coil 4 is fixed to the top wall 13 of the rotor 11, and the reading coil 2 is coaxially fixed to the top wall 12 of the stator 1. The two wires of the read and interrogation coil are wound on the center post of the opposing shroud ferrite core 26.

圖3之配置原則上與圖1所示相同，其中定子1包圍轉子11，讀取線圈2之罩形或E形鐵氧芯23被一U形鐵氧芯取代，讀取線圈之導線捲繞在其上。在此實施例中導線捲繞在U形芯體的底部，但其亦可捲繞在兩自由邊25上。The arrangement of Fig. 3 is basically the same as that shown in Fig. 1, in which the stator 1 surrounds the rotor 11, the cover-shaped or E-shaped ferrite core 23 of the reading coil 2 is replaced by a U-shaped ferrite core, and the wire of the reading coil is wound. On it. In this embodiment the wire is wound around the bottom of the U-shaped core, but it can also be wound on the two free sides 25.

圖4顯示一對旋轉對稱對立之線圈，即讀取線圈2與詢答線圈4。兩線圈之載體27由具U形截面之環形芯體24構成，其自由邊25彼此對立。Figure 4 shows a pair of rotationally symmetrically opposed coils, namely the read coil 2 and the interrogation coil 4. The carrier 27 of the two coils is constituted by a toroidal core 24 having a U-shaped cross section, the free edges 25 of which are opposite each other.

不同於圖1至圖4所示之環形線圈，詢答線圈在圖5中有利地設作平面線圈。導線14之一部分設在一薄膜15上，而構成平面線圈19之一部分。接點27設在薄膜15相對之面上。下一層設相同之接點，其在相對的面上，使得兩層相疊時一層之接點與另一層之另一接點接觸，其他兩接點則用於外接觸。如平面線圈之導線14為螺旋式，則一層中電流由外向內流，另一層相反。該平面線圈可構成讀取線圈亦可構成詢答線圈。線圈套到轉軸上時，不構成旋轉對稱之線圈。平面線圈覆蓋定子或轉子的範圍越大，能量的傳輸越均勻。Unlike the toroidal coils shown in Figures 1 to 4, the interrogation coil is advantageously provided as a planar coil in Figure 5. A portion of the wire 14 is disposed on a film 15 to form a portion of the planar coil 19. A contact 27 is provided on the opposite side of the film 15. The next layer is provided with the same contacts, which are on opposite sides such that the junction of one layer is in contact with the other contact of the other layer when the two layers are stacked, and the other two contacts are used for external contact. If the wire 14 of the planar coil is spiral, the current in one layer flows from the outside to the inside, and the other layer is opposite. The planar coil may constitute a read coil or may constitute a query coil. When the coil is sleeved on the rotating shaft, it does not constitute a rotationally symmetrical coil. The larger the range in which the planar coil covers the stator or rotor, the more uniform the energy transfer.

圖6係顯示兩層式平面線圈接觸之垂直截面圖。平面線圈下層28之接點27設作接觸丘30。兩層28,29壓緊時，接觸丘30伸入一相對的開口31中而接觸接觸面32，並可以適當方式與該接觸面32連接。Figure 6 is a vertical cross-sectional view showing the contact of a two-layer planar coil. A contact 27 of the lower layer 28 of the planar coil is provided as a contact dome 30. When the two layers 28, 29 are pressed, the contact dome 30 projects into an opposite opening 31 to contact the contact surface 32 and can be coupled to the contact surface 32 in a suitable manner.

如此可使任意多之平面線圈上下疊置，如圖7所示。特別有利於成本的是使設在一薄膜15上的平面線圈如圖8所示具多條並排之導線14。其末端33之接點27藉部份34之適當引導而與部份35之導線14錯開一距離，故環繞例如轉子時導線可作為繞組。該線圈在對角線的末端各具一外接觸端36。此種薄膜可適當裁剪以用於不同直徑。This allows any number of planar coils to be stacked one on top of the other, as shown in Figure 7. Particularly advantageous in terms of cost is that the planar coils disposed on a film 15 have a plurality of side-by-side wires 14 as shown in FIG. The contact 27 of the end 33 is offset from the wire 14 of the portion 35 by appropriate guidance of the portion 34 so that the wire can act as a winding around, for example, the rotor. The coils each have an outer contact end 36 at the end of the diagonal. Such films can be suitably cut for different diameters.

圖9係顯示平面線圈19設作如圖4所示讀取及詢答線圈之配置。定子1較佳係由導電性良好之材料製成，例如鋁。讀取線圈2與定子1間設一薄膜18，其較佳係由一鐵氧材料製成，尤其是厚度為0.2 mm之鐵氧薄膜，如Epcos公司之產品F96。薄膜與定子間可再設一厚度例如為0.05 mm的銅薄膜。讀取線圈2較佳為旋轉對稱之線圈，其在適當位置以適當方式與讀寫器連接。與其相對之詢答線圈4同樣由旋轉對稱之平面線圈19構成。詢答線圈與一般皆由工具鋼，尤其是工具機轉軸3，構成之轉子11間設一厚度為0.025 mm之薄膜17，其由具高磁導率之材料製成，亦即一非晶態軟磁性金屬，例如Vakuumschmelze Hanau公司之產品Vitrovac。Fig. 9 is a view showing the arrangement in which the planar coil 19 is provided as a reading and interrogation coil as shown in Fig. 4. The stator 1 is preferably made of a material having good electrical conductivity, such as aluminum. A film 18 is disposed between the reading coil 2 and the stator 1, preferably made of a ferrite material, especially a ferrite film having a thickness of 0.2 mm, such as the product F96 of Epcos. A copper film having a thickness of, for example, 0.05 mm may be further disposed between the film and the stator. The read coil 2 is preferably a rotationally symmetrical coil that is coupled to the reader in a suitable manner in place. The inquiry coil 4 opposite thereto is also constituted by a rotationally symmetrical planar coil 19. The acknowledgment coil is generally made of a tool steel, in particular a machine tool shaft 3, and a film 17 having a thickness of 0.025 mm is formed between the rotors 11 and is made of a material having a high magnetic permeability, that is, an amorphous state. Soft magnetic metal, such as Vitrovac, a product of Vakuumschmelze Hanau.

圖10係顯示讀取線圈2另一實施例之水平截面圖，其線圈8捲繞在一U形鐵氧芯7的自由邊25上。此處讀取線圈2容置在一鋁製殼體37內並被灌注材料38固定。讀取線圈2環境5亦可設另一材料，如結構鋼，但同樣較佳為鋁。定子1內壁帶狀設置上述薄膜18其在讀取線圈處39中斷。Figure 10 is a horizontal cross-sectional view showing another embodiment of the reading coil 2, the coil 8 of which is wound around the free side 25 of a U-shaped ferrite core 7. Here, the reading coil 2 is housed in an aluminum casing 37 and fixed by a potting material 38. The environment of the reading coil 2 can also be provided with another material, such as structural steel, but is also preferably aluminum. The inner wall of the stator 1 is provided with a strip of the above-mentioned film 18 which is interrupted at the reading coil 39.

圖11係顯示圖10線XI－XI之垂直截面圖。中斷之鐵氧層18在朝向定子1的一側另設一良好導電層22，例如由銅構成。旋轉對稱且軸向上明顯較細之詢答線圈4設在一環溝21中。設作平面線圈19之詢答線圈4與轉子11之間設已述高磁導率之軟磁性薄膜17，其軸向上的寬度大於詢答線圈4。Figure 11 is a vertical sectional view showing line XI-XI of Figure 10. The interrupted ferrite layer 18 is provided with a good electrically conductive layer 22 on the side facing the stator 1, for example of copper. The interrogation coil 4, which is rotationally symmetrical and substantially thin in the axial direction, is disposed in a ring groove 21. A soft magnetic film 17 having a high magnetic permeability described above is disposed between the interrogation coil 4 of the planar coil 19 and the rotor 11, and has a width in the axial direction larger than that of the interrogation coil 4.

如此可以習知詢答機系統之解析及傳輸技術使微晶片及感測器具足夠之功率，尤其是使成本低廉。詢答線圈軸向上之寬度一般為6 mm，設在定子與轉子間之薄膜的軸向寬度一般為7 mm。鐵氧層厚度為0.2 mm，高磁導率層厚度為0.025 mm便已足夠。此種平面線圈之厚度約為0.1 mm，工作頻率約為125 kH。Thus, the resolution and transmission technology of the interrogator system can be used to make the microchip and the sensing device have sufficient power, especially at a low cost. The width of the interrogation coil is generally 6 mm in the axial direction, and the axial width of the film between the stator and the rotor is generally 7 mm. The thickness of the ferrite layer is 0.2 mm, and the thickness of the high permeability layer is 0.025 mm. The planar coil has a thickness of approximately 0.1 mm and an operating frequency of approximately 125 kH.

詢答機系統使用其他頻率時可進行適當調整。如此得到之線圈組合即使用於機械製造之一般金屬環境亦可提供極高之品質。詢答線圈可配合負荷。依據本發明之方法只需一極小之發射線圈便可供應轉子上之微系統。發射線圈之一般尺寸為25 x 25 x 25 mm。當然亦可在一系統中組合多個線圈。The interrogator system can be adjusted as appropriate when using other frequencies. The coil combination thus obtained can provide extremely high quality even in a general metal environment for mechanical manufacturing. The inquiry coil can be used with the load. According to the method of the present invention, a micro-system on the rotor can be supplied with only a very small transmitting coil. The general size of the transmitting coil is 25 x 25 x 25 mm. It is of course also possible to combine multiple coils in one system.

線圈較佳為串聯諧振，其可在靜止及移動件之間達到特別良好之能量傳輸。已述方法相較於空心線圈可達到10倍以上的改良。The coil is preferably a series resonance that achieves particularly good energy transfer between stationary and moving parts. The method described can achieve an improvement of more than 10 times compared to the air-core coil.
